I've got a roll of Agfa ASP Surveillance (Rollei Retro 400s) with "excess length" (more than 36 exposures).
I think it's too long for fitting into my Jobo or AP cans directly.
Has anyone experinece how to develope such a film at home without cutting it blind into pieces?

Regards

how much longer than 36exposures? from my experience, most tank reels can take around 40 exposures and some (paterson - some models) even 42. I can ask friend who uses only bulk film and sometimes makes "longer" films - like 40/41 exposures.

If the film is much longer, I would search for some cine film developer - but those machines are ussualy for really long spools:/

Develop in total darkness inside a basin (as if it was a print - but NO red light!)
But try loading it into a reel first, maybe it still fits.

With most films, the maximum you can fit inside a 35mm canister is around 40 exposures. My Patterson and Nebro spirals will accomodate a lot more than will fit in a canister so I don't see a problem.

Thx! I will try to use my usual spirals (AP and Jobo) and if they are not big enough I will try it in a 1000ml beaker.

When I load a 36exp film onto one of my Patterson spirals, there is still loads of space left, not sure how many more exposures that space represents, but quite a few.

I hand load my films from bulk and no matter how tightly I wind them, I can't get more than 38 or 39exp, I think a little more is possible with a normal canister (I use reloadable ones) as the walls are thinner, and also, some films are thinner than the Kodak film I mostly use that has a thick estar base.

It says "50 exposures" on the film (refillable plastic canister) Rolling Eyes hopefully it will work

Hmm, I wonder how they managed to fit that much film inside?

In the 70s there was a double-length 72 exposure cassette (from Ilford, iirc), which while great value for money, would have been a total pita for home processing, as the reels simply weren't long enough. I suppose many labs just tacked it on like everything else, so the extra length wasn't a problem for them.
It used a thin polyester base, if memory serves, and was a bugger for curling. It was popular with motorwind users.

Why don't you cut it in two *before* loading it into the camera?
You'll get two rolls of approx. 24 exposures and no further problems.

I don't have any loading equipment or empty cans. The film would be lost.

did you photographed on that film yet or not? I don´t see problem in respooling half of it into used empty can - you just fix it to end of film leaved in the can and turn it into it - in darkness.

I didn't shoot it yet but I also don't have any reuseable cans or a non-destructive can opener Smile

I think I will simply try a basin or large flask with stopper.
Or I will risk to loose a good pic when cutting the film into two halfs after shooting it.

You don't have a changing bag? How do you load film into the spirals for developing?
You can cut and assemble a film also in a dark room, you just need a table, scissors, scotch tape, and a couple of rechargeable film cans (cost about 1 Eur each).

I have changing bag and bathroom without windows. But to buy an 1€ film can + shipment for a single 2,25€ film makes not much sense Wink

That stuff scratched dead easy, we used to d&p the odd roll when i worked in the trade.
